Vianney Halter – La Resonance

A RECOLLECTION OF A GALACTIC JOURNEY

This new piece results from a sequence of adventures through time and space. Vianney Halter worked many years on the acoustic resonance to express this phenomenon through the mechanics of watchmaking. Developing first the Deep Space Tourbillon and then the Deep Space Resonance was a crucial preliminary work that led to the conception of La Resonance.

In this new calibre, there is no more mainplate.  The bridges, pillars and large wheels take you to a new universe, where the genuine acoustic resonance phenomenon is highlighted.

La Resonance is a 3 hand, 35 grams light, round watch, regulated by two oscillators coupled by acoustic resonance.

The titanium 39mm case and 11mm thick is constructed of a unibody ring set with four separate lugs.  It is enclosed with 3 curved sapphire windows to ensure a 3D view of the in-house developed VH222 calibre.  The crown is unconventionally placed at 9h to offer a better sight on the technical architecture on the 3h side where the 3hz frequencies oscillators are located.  This 100 hour power reserve movement is composed of 320 hand finished parts, including 13 titanium bridges and 11 large wheels.  Their cumulated hand polished bevelled length is 3.7 meters. The 30 concave mirror-polished pillars hold the light structure which is fitted with 52 jewels. The manual wound twin barrels, converging in the differential allow the individual feeding of the coupled resonating balance wheels. Last but not least, the two oscillators are mounted in a modular porte-escapement unit.
